I recently installed kubuntu 22.04 on my acer spin 5 and tried to make the fingerprint sensor work. I managed to figure out that libfprint require me to swipe my finger across the sensor (which windows 11 does not, its a touch not a swipe). After I enrolled my fingerprint using fprintd-enroll everything seemed to work, no errors. Except when I tried to fprintd-verify, I can't get anything else than verify no match done.
I did some research and found that I was not the only one having issues, but I haven't found a solution that works for me.
Here is the sensor : Bus 003 Device 002: ID 04f3:0c4f Elan Microelectronics Corp. ELAN:Fingerprint
Using libfprint-2-2: Installed: 1:1.94.3+tod1-0ubuntu2~22.04.03
Can anyone help me ? Thanks a lot.
